Referring to the drawings, and particularly Figs. 1 to 3, a window frame adapted to be disposed in a window opening of a wall is provided with an extruded exterior tubular frame piece 1 adapted to be disposed exteriorly to a building wall. A window sill 2 is disposed on the base of the window opening and is separated from the concrete building wall 3 by caulking compound 4. The sides and top of the window are provided with a U-shaped frame piece 5 adapted to engage the building concrete wall top 6 and the building concrete side walls 7 and 3. An extruded longitudinal metal strip 9 is disposed between the sill of the window and the bottom of the exterior frame piece 1. Extruded longitudinal strips 11) are disposed between the top and the two sides of element 5 and the top and sides of the exterior frame piece 1. A U-shaped sealer tape 11, for example of synthetic rubber, is disposed between the extruded longitudinal members 9 and 1t! and the exterior frame piece 1.

As shown in Figs. 2 and 3, the cross section of the exterior frame piece 1 is provided with an integrally united and peripherally disposed L-shaped flange piece 12 adapted to engage the sealer tape 11 in weathertight relationship. The frame piece 1 is further provided with an integrally and peripherally disposed T-shaped flange piece 13. A plurality of U-shaped longitudinal flange metal strips 14 are secured to the top and bottom of the window opening by conventional means, for example, bolts 15, to a concrete wall structure 16. The said U-shaped members 14 are secured to the said elements 10 through a bracket arrangement of conventional manufacture, generally shown by the numeral 29. A framing plate 17 is disposed on all four sides of the window opening and secured by means of bolt and nut assemblies 18 to the elements 14 and the top of the T-shaped element 13. A plurality of insulating flat plates 19, for example, Micarta plates, are disposed be tween plates 17 and the T-shaped flange pieces 13. The window frame may also be supplementally supported at its top by means of conventional bracket assembly, generally shown by the numeral 21.

A window sash, generally designated by the numeral 23, Figs. 3 and 12, is made from longitudinal extruded aluminum elements. An exterior tubular longitudinal sash element 23x is provided with an integrally united caulk retaining flange 24. An interior tubular extruded metal sash element 25 is disposed interiorly of the element 23x. The elements 23:: and 25 are provided with screw receiving apertures. A plurality of plastic plates, for example, Micarta plates 26, are disposed between the sash elements 23x and 25. A plurality of screws 27 are disposed between the elements 23 and 25 and through suitable apertures located in plastic elements 26.

A removable plate 23 provided with a flanged edge 29 is adapted to be keyed into a coacting groove disposed in the sash piece 25. Removal of the plate pieces 28 prevents removal of the lass window panes from the sash. The removal plate 28 is secured to the inner tubular sash elements 25 by means of a plurality of screws 31 (Fig. l). The sash 23 is provided at its top and bottom with U-shaped pivot receiving thimbles 32, said thimbles 32 being disposed between the exterior sash element 231' and interior element 25; r I

A cylindrical pivot pin '33 is centrally disposed in the bottom sash and top sash frame pieces and disposed upon the corresponding T-shaped element 13.

Turning to Figs. 4, 5 and 6, an e'xpansible window frame, generally designated by the numeral 3 consists of four independent U-shaped movable members adapted to be moved toward and away from .each other simultaneously as a unit. The four U-shaped members consist of a'top U-shaped member 35, a bottom U-shaped member 36, and a pair of lateral U-shaped members 37.

The T-shaped flange 13 of the tubular window frame 1 is provided with a plurality ofcam members in the form of slotted flanges 35 at those portions of the flange 13 disposed opposite the vertical movable U-shaped members 37. The slotted flanges 38, Figsn4 and 5, disposed on opposed sides of the'window opening, have angular slots 39 disposed therein. As can be seen from Figs. 4 and'S, the slots disposed on the opposed sides of the window converge toward a common line.

The U-shaped vertical window frame members 37 are provided with a plurality of abutments such as pins 40, which pins are disposed in the opposed legs of the U- shaped member and adapted to engage the slots 39 of corresponding flanges 38.

A pair of corner travel links 41 are secured adjacent the bottom of each of the U-shaped members 37 and adapted to actuate the members 37 selectively upwardly or downwardly. The selective upward and downward motion of the members 37 is modified by the travel of the pins 30 secured to the members 37 so that an inward and outward movement is simultaneously effected with the upward and downward movement due to the travel of the pins in the'slots 39.

A hand operated worm wheel 42 (Figs. l7, l8 and 19) is secured to a housing 43. lnteriorly of the housing 43 is disposed a worm gear 44 adapted to engage with a co-acting worm gear disposed on worm wheel 42. The worm wheel 42 is' provided with a rotatable finger grasp 45 (Fig. 14). The worm gear 44 is connected to a lef handed threaded rod 46 and a right-handed threaded rod 47. The rod 46 is secured to a travel block 48 having a front apertured wall 48a adapted to receive the lefthanded threaded rod 46, the lateral sides of which are provided with an inclined ledge 49. An abutment in the form of a rider pin 59 is fixedly disposed in the bottom U-shaped member 36 adjacent the inclined ledge 49 and adapted to be pushed upwardly or downwardly by riding upwardly or downwardly upon the inclined ledge 49. The motion of the pin 56 vertically upwardly or downwardlynecessarily causes the U-shaped member 36 to move upwardly or downwardly depending upon the lateral motion of the travel block 48. A threaded left bolt 51 is fixedly secured to the rear wall 52 of the travel block 48. This left bolt 51 is secured to a left hinge block 53.

.The right-hand threaded travel rod 47 is secured to a right threaded travel block 54 and having a front threaded apertured wall 55 adapted to receive the right threaded rod 47. The block 54 is also provided with a rear threaded wall 56 adapted to receive the fixedly secured bolt 57, said bolt 57 being in turn removably secured by conventional means, for example, pins 58, to a right hinge block 59. The corner travel levers 41 are secured respectively to the left or right hinge blocks 53 or 59.

A pair of support plate 60 are fixedly secured as, for example, by welding, adjacent the extreme ends of the U-shaped window frame member 36, and are provided with apertures to receive apertured links 61. The links .61 are secured in turn to the respective corner hinge blocks 53 and 59. In the operation of this window toeifect movement of the window U shaped frame members 35, 36 and 37 toward a central point or toward the window sash, rotation of the worm wheel 42 effects rotation of the worm gear 44, which gear 54 is in turn fixedly secured both to the left-handed threaded travel rod 46 and to the right-handed threaded travel rod 47. This rotation of the worm gear 44- causes the travel blocks 48 and 54 to simultaneously move inwardly or outwardly, depending on the direction of rotation of the worm gear 44. in other words, the threaded rods 46 and 47 cause movement of the travel blocks 48 and 54 toward or away from the fixed yoke 43. The movement of the blocks 43 and 54 causes movement of the respective corner hinge blocks 53 and 59, and since these hinge blocks are linked by means of the parallel travel links 4 to the vertical Ushaped window frame members 37, it follows that lateral movement of the blocks 53 and 59 affects a vertical movement of the frame members 37, which vertical movement of the frame members 37 is modified in part to a lateral movement due to the sliding effect of pins 4 1? in slots 39 of the flanges 38, which slots act as cam members.

Simultaneously with the movement of the blocks 48 and 54, the inclined ledge 49 of the travel block 48 causes the pin 50 to ride upwardly or downwardly so that the bottom U-shaped window frame member 36 is accordingly moved upwardly or downwardly. This upward and downward movement of the bottom frame member 36 is assisted by the movement of the links 61 so that the closing effect of the frame member 36 against the window sash is firm and positive.

In order to affect a downward and inward movement of the top frame member 35 simultaneous with an upward and inward movement of the bottom frame member 36, the U-shaped frame members 37 are linked to theframe member 35 by means of a pair of right angle plate pieces 62. The plate pieces 62 are fixedly secured along one leg to their respective U-shape-d frame members by conventional means, for example, rivets 63. The other leg of the right angle plate pieces 62 is provided with slots 64. V

A pair of spaced apart blocks 65 are fixedly secured, for example, by metal screws 66, to the top T-shap'ed flange 13 of the corresponding top section of the frame piece 1. face 67 disposed respectively away from the pivot pins 35. A movable block 68, having a tapered or inclined top face 69, is disposed adjacent the block 65 with the face 67 of block 65 slidingly engaging the face 69 of travel block 68. Blocks 68 and 69 serve as cooperating cam members.

The travel block 68 is provided with a rod 70 securely disposed in an aperture in block 68. The rod 70 (Fig. 20) is provided at its free or unsecured end with an end block 71 having a longitudinal slot 72 thereimthe axis of the slot being disposed linearly with the rod 70. A pin 73 is disposed within the slots 64 of the parallel plate pieces 62 at each corner of the window frame and through the slot 72 of the end block 71.

The loose arrangement of pin 73 within the slots 64 permits an upward movement of U-shaped window frame member 35 with asimultaneous upward and outwardmovement of lateral U-shaped window members 37. Clearly, therefore, the motivating mechanism-of this'invention shown in Figs. 4 and 5, and showing the movable U-shaped window frame members in open position (Fig. 4)- and closed position (Fig. 5), affects an upward and downward movement of th top and bottom U-shaped frame members 35 and 36, and a corresponding movement of the members 37.

A continuous peripheral weather strip 74, having the preferred configuration shown in' Fig. 15, issecured in the window frame piece exteriorly of the movable U- shaped window frame members 35, 36 and'37. .Apertures are provided in the continuous weather strip 74,

The blocks 65 are provided with an inclined both at the top and bottom thereof, to permit passage of the pivot pin or rod 33 therethrough.

The weather strip 74 2) is clamped to the exterior tubular frame pieces 1, and the corresponding interior elements 17, by means of longitudinal T-shaped clamping plates 75 disposed securely to both edges 76 of the weather strip '74-. Clearly, therefore, when the window sash 23 is disposed within the circumferentially and peripherally disposed weather strip 74 (Fig. 2), simultaneous actuation of the U-shaped window frame movable members 35, 36 and 37 clauses an inward movement of the corresponding sections of the weather strip 74 to affect a firm weather-tight seal between the weather strip 7 and corresponding ridges 77 of the sash 23. In order to affect a locking of the window sash 23 in place relative to the window frame, the sash is provided with ear of hinge lock bars 78 (Figs. 1 and 11).

The lateral U-shaped members 37 are provided with is '7? to permit travel of the locking bar 78 therein and to engage the fixedly disposed lock pin 80 disposed between th legs of the U-shaped member 37. The loci; pin 73 is provided with a slot, not shown, adapted to engage the lock pin 30 in locking relationship. The lock pin 73 is disposed centrally within the sash 23 (Fig. ll) and adapted to be rotated through an arc by means of a key (not shown), adapted to engage a rotatable barrel The pin 78 is keyed to the rotatable ba rel 31 by means of an insertable key 82, edly disposed between the barrel 81 land the locking The barrel S1 is disposed in an apertured sash cer 33, and is provided with ends adapted to eng key from either side so that the window may be ene from the interior of the building or from the aterior of the building, as by firemen in case of fire.

In order to prevent pinching of the weather strip 74 t the corners of the movable U-shaped frame members 5, 35 and 37, a plurality of freely slidable U-shaped corner elements 34 are disposed in each of the four corners between the respective movable U-shaped elements and the weather strip 74. Clearly, the weather strip 7% is net clamped to the window frame members at the corners so that there is free sliding movement of th corners against the base of the corresponding U-shaped members.

As shown in Figure 10, the tubular sash members 23;: 25 may be provided with filler block 85, for example, soft metal or equivalent material, and screws 86 le 32. The use of the filler block 85 afiects a strong construction about the thimble 32, which .tmble supports the weight of the sash.

As shown in Fig. 15, the weather strip 74 is provided with a pair of parallel disposed circular apertured pressure engaging sections 87 adapted to engage the pressure ridges 77 of the sash.

While this invention has been described by means of a single embodiment, it will become apparent to those skilled in the art that the generic scope of this invention embrace all window frames having peripherally disposed resilient weather strips motivated by pressure bars disposed about said peripherally and circumferentially disposed weather strip.
